It will be interesting to see if the R50 develops any noise, like the R65 did, with the current 20" Vario 4 blade you are now running. I don't believe the R50 has a center bearing either. Any plans...

Steve, weren't you using the Vario Prop 22" 4 blade before with the R65 motor? So you have switched to the 20" (roughly) 4 blade with the above results, correct?

Thanx for the info Greg. Have you tried any 4 blade props with the TR50 (Turnigy Rotomax 50)? These large 4 blades seem to be giving these motors a run for their money. That is our goal, to find a...

SJ, have you noticed this ringing noise issue with the R50 motor, or just with the R65? I was watching a number of videos with the R65, R50, and the P360 and the R65 seemed the noisiest. The P360...

SJ, yes, I read that about the EFlite 360 as well. More learning, that's good. How are the bearings in your R65? Maybe they are causing the vibe issues. I just bought a new R65, however, and I still...

SJ, any new data with any new props and the R65 setup? I am thinking about buying the Biela prop as you did. There is not a lot of choice out there for adj pitch props, unfortunately.
